Menopause, or the cessation of menstrual periods, generally occurs in the 40s and 50s and marks the cessation of fertility, although age-related infertility can occur before then.
Silky lupine grows in northern areas from Washington and Oregon east to South Dakota. Tailcup lupine is found in Oregon, California, Idaho, Utah, Montana, and Wyoming. Velvet lupine is found in an intermountain region from Oregon to Wyoming. Silvery lupine occurs from North Dakota and Idaho south to Arizona and New Mexico.
The flowers come in a wide range of colors and bloom throughout summer. Lupines grow up to 4 feet tall and 2 feet wide with horizontal leaves and 1- to 4-foot-tall flower spikes that contain small blossoms that resemble those of pea plants. The lupine grows wild throughout most of the colder regions of the United States and prefers to grow in climates where summer nights are cooler. Lupine plants are short-lived and grow best in USDA hardiness zones 4 through 7, where winter temperatures can dip down to minus 25 degrees Fahrenheit.
